  1. 1. Gas flow sputtering of Cu(In,Ga)Se2 with extra selenium supply

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Marcus Turunen; [2015]
    Keywords : Gas flow sputtering; CIGS; selenium; thin film; solar cell;

    Abstract : In this thesis CIGS absorber layers have been deposited by gas flow sputtering with an extra supply of selenium, a method that displays promise for large scale production because of its one-step sputtering route which deposits low energy particles in a high deposition rate. In this thesis a method was developed where selenium was added to the sputtering process inside the sputter chamber in a controllable manner and in larger amount than done in previous projects.

    Abstract : Graphene has been shown to be very powerful as a transducer in many biosensor applications due to its high sensitivity. This enables smaller surfaces and therefore less material consumption when producing sensors and concequently cheaper and more portable sensors compared to the commercially available sensors today.

  4. 3. Deposition of CIGS absorber layer by gas flow sputtering : Initiation of project

    University essay from Fasta tillståndets elektronik

    Author : Anders Åsberg; [2013]
    Keywords : GFS; gas flow sputtering; CIGS;

    Abstract : The photovoltaic solar cell industry is growing rapidly, but high cost per watt is still an obstacle. Thin film solar cells, especially thin film solar cells using CIGS absorbers that have the highest proven efficiency, have the potential to reduce the cost through cheap manufacturing. READ MORE
